3 Claims.

This invention relates to rolls for use in drying apparatus, warp slashing machines and other textile machines, and the invention may be embodied in a ribbed rol1,'that is, one which is provided on its exterior with ribs extending longitudinally thereof, or it may be embodied in a roll having a smooth surface.

Sometimes rolls of this type are made with an exterior surface of non-corrosive material, or if the roll is a ribbed roll, the ribs are sometimes made of non-corrosive material.

One known way of making such a roll is to provide a tubular cylinder of a length equal to that of the completed roll and of a diameter approximately that which the roll is to have, and then to cover the cylinder with a sheet metal envelope which is rigidly secured thereto in some suitable way.

If the roll is to have a non-corrosive exterior surface, then this sheet metal envelope is made of non-corrosive material, and if the roll is to have ribs on its exterior, then these ribs may be formed in the sheet metal envelope.

One of the objects of my present invention is to provide a novel roll which may or may not have ribs extending longitudinally thereof and which may or may not have its exterior surface formed of non-corrosive material, but which, nevertheless, will be considerably lighter in weight than a roll of the same size made as above described and which will also be substantially as rigid as a roll formed by covering a tubular body member with a sheet metal envelope.

A further object of the invention is to provide a hollow roll of this type in which the shell is made up of a plurality of strips or sections of sheet metal that are assembled and interlocked together to form the completed roll. If the roll is to be a ribbed roll, then these separate sections may each be preformed with a rib extending longitudinally thereof so that when the sections are assembled to form the shell of'the roll, the completed roll will have a plurality of longitudinal ribs on its exterior. If the roll is to have an exterior surface of non-corrosive material, then the sheet metal sections will be made of such non-corrosive material.

Further objects of the invention are to provide various improvements in rolls of this type, which will be more fully hereinafter set forth.

In the drawings, wherein I have illustrated a selected embodiment of my invention:

Fig. 1 is a longitudinal section through a. roll which is made in accordance with the invention,

said figure illustrating one embodiment of the invention.

Fig. 2 is a view of one of the interior supporting disks of the roll shown in Fig. 1, said disk being shown on a larger scale than in Fig. 1.

Fig. 3 is a view of one of the end disks of the roll, shown in Fig. 1, said disk also being shown on a larger scale than in Fig. 1.

Fig. 4 is an enlarged sectional view on the line 4-4, Fig. 1.

Fig. 7 is a fragmentary perspective view similar to Fig. 5 but showing a different form of sheet metal strip. I

Fig. 8 is a cross-sectional view through a cylindrical roll made from strips similar to those shown in Fig. 7.

Fig. 9 is a view of one of the end disks used in the roll shown in Figs. 8 and 10.

Fig. 10 is a fragmentary perspective view of the end of the cylindrical roll shown in Fi 8.

Fig. 11 is a fragmentary perspective view of a sheet metal strip from which a cylindrical roll having ribs may be formed.

The body portion of my improved roll is made up of a-series of sheet metal strips extending longitudinally of the roll, each of which strips is so shaped that it may be interlocked at each edge with an adjacent strip. When a plurality of these strips are assembled with their edges connected together, they constitute the body of the cylinder or roll, and if these strips are made of some non-corrosive material, such as brass or stainless steel, the completed roll will have a non-corrosive surface.

If the roll is to have ribs extending longitudinally thereof, then some or all of the sheet metal strips may be deformed to provide the ribs.

In Fig. 5, there is shown at 1 a preformed sheet metal strip such as may be used in making one form of ribbed roll embodying my invention. This strip is formed from sheet metal which has been deformed to provide the outwardly directed rib 8 which extends longitudinally of the strip from one end to the other, and one edge por tion of the strip isbent inwardly to form the inwardly extending wing 9. The other edge of the strip is also bent inwardly, as shown at ill and then is bent back on itself, as indicated at H, thereby forming a longitudinal groove or pocket I2 between the portions I and II. This pocket I2 is of a width to receive the wing 9 of an ad- Jacent strip. The wing 9 may be referred to as a single edge and the portions I0 and II as a double edge. The inbent single edge and double edge portions 9, I0 and I I have an angular relation to each other, so that when a plurality of these strips are assembled by inserting the wing or single edge 9 of one strip into the pocket I2 of the double edge of an adjacent strip, the assembled strips will form the shell of the roll.

In the construction herein shown in Figs. 1 to 4, there are twelve of such strips I interlocked together to form the surface of the roll, and hence the roll will have twelve ribs 8.

These assembled strips 1 are maintained in their assembled relation by means of disks situated within the roll and which are mounted on a central shaft I3, preferably a tubular shaft. There are two end disks Il, one at each end of the roll, and a plurality of intermediate disks I5, the number of which are dependent somewhat upon the length of the roll. These disks may be polygonal in shape, as shown in Figs. 2 and 3, and thus provided with flat faces I6, or they may be circular in shape, as shown in Fig. 9. If the disks have a polygonal shape, I will preferably make each strip I with the two flat or straight sections II, one either side of the central rib 8, which flat sections II have the correct angular relation to each other so that they rest on the two adjacent flat faces I6 of the disks I4 and I5. The intermediate disks I5 are each formed with a plurality of slots I8, there being one slot extending inwardly from the median point of each flat face I6. Each slot I8 is of a size to receive the inbent double" edge portion III and of a strip 1, and when the disks I5 are assembled with the connected strips I, the interlocking edges of adjacent strips occupy the slots I8 of the disk I5, as clearly shown in Fig. 4.

The end disks Il are made to set within the shell of the roll, and in the construction shown in Figs. 1 to 5, they are made without .any slots. Hence, in order to accommodate the disks Il, the ends of the inbent portions 9, I0 and II are cut away slightly, as indicated at 20 in Fig. 5, the amount which these inbent portions are cut away being substantially equal to the thickness of each end disk Il. When the end disks Il are in place, therefore, the ends of the flat portions II overlie the flat faces I6 of the disks Il, and the inner faces of the disks Il rest against the edges 20 of the inbent portions 9, I0 and I I.

The end disks Il are permanently secured in some suitable way to the roll body (which is made up of the assembled sheet metal strips 1), and one convenient way of accomplishing this is by welding the head or end disk Il to the ends of the sheet metal strips, as indicated at 22.

The end disks Il are also preferably welded to the central shaft I3, as indicated at M, and the intermediate disks I5 are also preferably rigidly secured to said shaft I3, as by means of welding.

There is shown in Fig. 1 a plurality of collars 23 mounted on the shaft I3, said collars being welded or otherwise secured to the shaft and forming means for-positioning the intermediate disks I5. The roll, when completed, will be provided with trunnion members 2l which are secured to the ends of the shaft III or may be made integral therewith, said trunnions providing means for rotatably supporting the roll.

In Figs. 7 to 11 I have shown a roll embodying my invention having a cylindrical surface rather than a flat-sided surface such as the roll shown in Figs. 1 to 4. In making a roll having 9. cylindrical surface, the strips, indicated at Ia from which the roll is made, will each be curved transversely on an arc corresponding to the curvature of the cylindrical roll, Each strip la is also provided along one side with the inwardly bent single edge or wing 9a, and at the other side with the inwardly bent double edge Ilia, IIa, which provides the pocket IZa to receive the single edge 9a of an adjacent strip. These curved strips are assembled in the same way as described with reference to Figs. 1 to 4 to produce the surface of the roll. The end disks Ila and intermediate disks I5a are circular in shape and have a peripheral curvature corresponding to the curvature of the strips Ia so that these strips, when assembled, will fit the peripheries of the disks. Both the end disks Ila and the intermediate disks I5a are provided with radial slots l8a at their peripheries to receive the interlocked edges 9a, Ilia, Ila of adjacent strips. These disks Ila and I5a are mounted on a central shaft [3a and are preferably welded thereto. In this construction, the ends of the single edges 9a and double edges Na, Na, project through the end disks Ila and come flush with the outer surface thereof. The ends of the strips Ia will preferably be welded to the end disks Ila, and if desired, the adjacent strips may be welded together at their meeting edges, as shown along the seams 21 where the edges of adjacent strips meet.

In Figs. 7 to 10, the strips Ia have smooth exterior surfaces. If it is desired to build a cylindrical roll with ribs extending longitudinally thereof, then I propose to use sheet metal strips 'Ib such as shown in Fig. 11. These strips are curved the same as the strips Ia shown in Fig. 7, and each strip is bent along one side to provide the single edge 9b and is bent along the other side to provide the double edge Ilib, IIb, and to form the pocket I211.

The curved strip 1b is deformed to present a rib 8a extending longitudinally thereof. A roll made up of the strips lb, such as shown in Fig. 11, will be a cylindrical roll that has a plurality of ribs 8a extending longitudinally thereof.

The ribbed rolls, such as shown in Figs. 1 to 4, and such as would result from the use of the ribbed strips, shown in Fig. 11, are especially adapted for use in slashing machines for supporting the wet warp threads as they emerge from the sizing bath, and also in other textile machines where a roll is required for supporting wet threads or wet cloth. The presence of the ribs hold the wet threads or wet cloth out of contact with the surface of the roll and thus prevent such wet threads or cloth from sticking to the roll surface.

For use in driers or other textile machinery where the presence of ribs on the roll is not necessary, then the plain surface rolls such as shown in Figs. 7 to 10 may be employed.

A roll embodying my invention is relatively light in weight for its size and is also a very rigid roll. It can be easily manufactured by the assembly method since the various parts ofwhich the roll is made can be readily formed from sheet metal and the assembly of the parts does not involve highly skilled labor.

Ifit is desired that the roll should have a surface of non-corrosive material, then the strips 1' will be formed from non-corrosive sheet metal, and when they are assembled to make the complete roll, the latter will have a surface of noncorrosive material.

I claim:

1. A roll for textile machines comprising a plurality of sheet metal sections, each extending lengthwise of the roll and each having its longitudinal edges bent inwardly, the inwardly bent portions at the meeting edges of two adjacent sections being interlocked, an end disk fitting within the assembled sections at each end of the roll and secured thereto, a plurality of intermediate disks fitting within the assembled sections, each intermediate disk having radially extending slots at its peripheral portion to receive the interlocked portions of the adjacent sections, and a shaft extending axially through all of said disks and on which the roll is supported.

2.
